Liquid leakage detection device and blood purification device

Technical Field

Background

The continuous kidney replacement therapy (CRRT) is a device for purifying blood by introducing blood of a patient to the outside of the body and removing certain pathogenic substances from the patient through a matched consumable, and the main treatment modes include hemodialysis, hemofiltration, hemodiafiltration, hemoperfusion, plasmapheresis, immunoadsorption, peritoneal dialysis, and the like. At present, blood purification therapy is not only used for treating patients with acute and chronic renal failure, but also widely applied to the rescue treatment of patients with acute and severe diseases.

When CRRT carries out blood purification treatment, in order to improve the safety of treatment, for example, in order to reduce the risk of blood coagulation caused by the contact of blood in a pipeline and air, and the like, liquids involved in the treatment process, such as replacement liquid, blood, plasma and the like, are all in a closed pipeline or a container isolated from air; in addition, a CRRT is generally provided with an accurate weighing system for monitoring the weight change of various liquids in the blood purification treatment process and adjusting treatment parameters such as flow rate, pressure and the like according to the weighing result of the weighing system. If liquid leaks in the treatment process, the probability of blood in the pipeline contacting with air to coagulate blood and generate thrombus is increased, and the safety of treatment is reduced; on the other hand, the accuracy of the liquid weighing system is influenced, so that the setting of treatment parameters is not matched with the actual situation, and the treatment result is influenced; leakage of liquid can also cause environmental pollution.

Illustratively, the first direction is the direction indicated by X shown in the drawing.

The leakage detection device 100 provided by the utility model can detect whether leakage flows out of the device body of the blood purification device or not by arranging the leakage detector 30; by arranging the supporting seat 10 with the bearing groove 11, leaked liquid can be collected in the bearing groove 11 after flowing to the supporting seat 10; by providing the inclined receiving surface 1111 on the groove bottom wall 111, leaked liquid can flow after dropping on the receiving surface 1111, thereby facilitating collection; the leakage liquid can be prevented from flowing out of the receiving tank 11 by arranging the tank side wall 112; by providing the leakage detector 30 at the lowest portion of the receiving groove 11, when the leakage drops on the receiving surface 1111 and flows to the lowest portion, the leakage detector 30 can quickly detect the leakage collected at the lowest portion, and the leakage detection efficiency can be improved; the lowest part of the receiving groove 11 is arranged in the middle of the receiving groove 11 perpendicular to the first direction, so that liquid in the receiving groove 11 can be conveniently collected to the lowest part, and when the liquid leakage detection device 100 is placed on an uneven bearing surface, for example, the bearing surface is provided with a small pit or a small bulge, so that one side of the liquid leakage detection device 100 is higher, if the side of the liquid leakage detection device 100 perpendicular to the first direction is higher than the other side, liquid can flow to the lower side after dropping on the higher side and can inevitably flow through the lowest point of the receiving groove 11, so that liquid leakage on the higher side can be collected and detected, and compared with the case that the lowest point is arranged at the end of the receiving groove 11 perpendicular to the first direction, the probability of collecting liquid leakage is improved, and liquid leakage can be detected more effectively. Therefore, the leakage detection device 100 provided by the utility model can quickly and effectively detect leakage.

Referring to fig. 4-5, the angle α between the receiving surface 1111 and the horizontal plane is 12 ° to 18 °. In practical application, the liquid leakage detection device 100 is usually placed on a horizontal bearing surface (such as a horizontal ground surface) to work, that is, an included angle α between the bearing surface 1111 and the horizontal plane is an inclination angle when the bearing surface 1111 works, and when the inclination angle when the bearing surface 1111 works is set to 12 ° to 18 °, the liquid leakage detection device 100 is beneficial to bearing and collecting liquid leakage; if the inclination angle is reduced on the basis, leakage can be received, but the leakage is not collected easily; if the inclination angle is increased on the basis, although the collection of the leaked liquid is facilitated, the collection of the leaked liquid is not facilitated. In a preferred embodiment, the receiving surface 1111 is at an angle α of 15 ° to the horizontal.

Referring to fig. 1, the receiving surface 1111 includes a first side 113 and a second side 114 arranged along a first direction, and the first side 113 is arranged near the carrying portion 20; the receiving surface 1111 extends from the first side 113 to the second side 114 in a downward direction, and the lowest portion of the receiving groove 11 is located on the second side 114.
